This example recreates a Sol LeWitt wall drawing as a visual grid of alternating horizontal and vertical lines, with a circular void cut through the center to reveal a layered, woven effect. The rendering uses D3 selections and the `.join()` method to generate and update SVG `<rect>` elements across the full canvas. Two SVG `<mask>` definitions combine black and white circles and rectangles to selectively hide portions of the line groups, creating the illusion of intersecting bands around an empty circle. The result is a clean, geometric composition driven entirely by D3’s data-binding utilities.
